Loctronix Gains Patent for Its Spectral Compression Positioning, Tracks CDMA, GNSS

Loctronix SCP technology

[Updated 4/26/09] On March 31, the U.S. Patent Office granted Loctronix Corporation its first patent, which will provide the foundation for its Spectral Compression Positioning (SCP) technology that enables multi-source positioning capability in a single sensor. Subsequently, the company announced that it had successfully achieved meter-level ranging performance using CDMA cellular signals.

Highlights of the 2009 Munich Satellite Navigation Summit (March 3- 5):
Russia will place its first CDMA signal on the GLONASS L3 frequency that overlaps the European Galileo E5b spectrum; China plans to launch three Compass satellites this year and seven more next year to provide a regional capability for Compass/Beidou, followed by completion of the full 30-MEO, 5-GEO constellation after 2015 and before 2020; Galileo program discussions revealed tensions around negotiations with China about a frequency overlay of Compass signals on the security-oriented Public Regulated Service as well as the question of whether the costs to build Galileo can be kept within the €3.4-billion limit agreed by the European Council and the European Parliament; the GPS Block IIR-20(M) satellite with an L5 demonstration payload will be launched later this month in what may be the program’s last chance to secure primary GPS access to the frequency.

GNSS Vulnerabilities and Solutions Conference 2009

The 2009 GNSS conference will focus on problems and vulnerabilities, and in particular, on developments aiming to improve the accuracy and reliability of the various GNSSes. It will take place on the resort island of Krk during the Adriatic high season.

Two special sessions will be organised in order to address particular causes of GNSS vulnerabilities: Space Weather and Ionospheric Effects on GNSS, and Safety Critical Applications (concerning primarily the ITS).

Satellite Collision Raises Issue of Similar GNSS Risks

GPS Orbital Decay. Aerospace Corporation

The February 10 collision of an active Iridium satellite and a defunct Russian military communications satellite underlines a concern raised recently at the International Committee on GNSS (ICG) about the need to include coordination of space vehicle (SV) operations.

In comments during a session of Working Group A (compatibility and interoperability) during the ICG’s recent meeting in Pasadena, California, Professor Grigory Stupak of the Russian Institute for Space Device Engineering (RISDE), noted that Russia’s “position is that compatibility includes more than just signals,” among other things, “the sharing of orbits and disposal of satellites.”

Similar concerns have been expressed in recent years by organizations that have studied the possibility of GNSS satellites, particularly those that have been “parked” in disposal or graveyard orbits, to drift and possibly collide with one another.

GNSS Providers Working Group to Discuss Compatibility, Interoperability

Munich Residenz in Germany, site of the ICG meeting.

The International Committee on GNSS (ICG) working group on compatibility and interoperability will meet March 2 and 3 at “der Residenz” in Munich, Germany.

The meeting, which takes place immediately before the Munich Satellite Navigation Summit 2009, follows on the most recent gathering of the full ICG and Providers Forum in Pasadena, California, last month. (Presentations from that meeting can be found here.) The Munich discussions will focus on compatibility and interoperability issues and system/service characteristics, such as current and planned signals, system time and geodetic reference frame standards, performance standards and actual system performance, service provision policies, and deployment and operation timetables.
